Memory points
Locations you go to
frequently can be stored
into memory and marked
on the map. The system
can store up to 200 points.
You can add icons at the
memory points so that the
system also displays the
icons on the map.
Motorway-preference selection
When searching for routes with the navigation
system, you can switch between searching for
routes that give priority to motorways and those
that give priority to ordinary roads. When you
specify motorway preference, the navigation
system automatically searches for a route that
gives priority to motorways and guides you along
that route.
Navigation terminology
Preface
Navigation
The navigation system displays and tracks the
vehicle’s position and movement on a moving
map display. When a destination is input, the
navigation system quickly calculates a route and
guides you along the route with pictorial displays
and voice prompts.
Current vehicle position
The navigation system integrates the GPS (Global
Positioning Satellite) signals received and the map
information stored on the DVD ROM to display the
position and direction of the vehicle. The system
also includes a gyroscope and a speed sensor
that enable it to display the present position even
in locations where the GPS signals may be
blocked.
Memory point mark
Map matching
Since GPS navigation has an error of 100 – 655
feet (30 m – 200 m), the position of your vehicle
may be displayed off the road. Map matching
automatically corrects this error so that the
position of your vehicle is displayed on the road.
Destination
The point on the map that
is your destination is
specified and displayed
with the destination icon.
You can set up to 5
destinations for the same
journey.
Route
When a destination is
input, the navigation
system automatically
calculates a route and
displays it in blue on the
map.
